Households in Great Britain ‘could owe energy suppliers £7bn by end of year’

Domestic energy arrears in Great Britain have reached concerning levels, with an industry trade association projecting significant increases as winter approaches. The trade group Energy UK reported that household energy debt climbed approximately £500m over the past year, reaching £6bn at the end of June. The organization now forecasts this figure could accelerate to £7bn by the end of the year, driven by ongoing geopolitical factors affecting global energy markets.

The anticipated rise in household energy costs stems from an expected increase in the government’s energy price cap set for October. The cap is projected to climb 4% from current levels, marking a three-year high. Industry analysts at Cornwall Insight predict the typical household will face annual gas and electricity bills equivalent to £1,729 during the final quarter of the year under the new cap structure. The forecasters estimate electricity rates will increase from 26.11p to 26.57p per kilowatt hour, while gas charges will rise from 7.33p to 7.90p for households using direct debit payment methods.

Energy UK’s leadership has called on the government to implement longer-term solutions to address rising energy bills, advocating for a social discount tariff rather than relying on temporary measures. The group noted that the new government’s plan to reduce VAT on household electricity bills starting in October will provide only modest relief, with savings of approximately £45 annually falling well short of offsetting the price cap increase. The organization emphasized that current arrangements fail to adequately assist struggling households and prove costly overall.

The projected energy costs are being driven primarily by wholesale gas market prices, with geopolitical tensions continuing to stoke increases. Additionally, expenses related to upgrading Great Britain’s energy infrastructure are playing a larger role in determining overall energy pricing. The trade association’s debt estimates exceed official figures reported by the regulator Ofgem by approximately £1bn, as the organizations use different methodologies for calculating arrears. Current arrangements result in unpaid energy bills adding roughly £50 annually to typical household energy costs.
